Those references below offer more detail regarding the default startup changes beginning with version 3.3.10. It is important to remember that all such changes were supposed to impact only new users or users who had not saved the personal config file (via that 'W' command). However, I introduced a bug wherein the rcfile was not fully honored. This gave the changes a bad reputation. That bug was corrected in release 3.3.11 but the issue of default startup options keeps resurfacing. And it's clear there's no consensus on what should be included. Our --disable-modern-top configure option is of little help since it remains an all-or-nothing approach. What we need is an answer offering unlimited customization. So, this commit will provide distribution packagers or system administrators with a much more flexible way to set their own preferred startup default configuration. A new rcfile is being introduced: '/etc/topdefaultrc', whose format/content is the same as a personal rcfile. Thus once a 'proper' enterprise configuration has been established and saved via 'W', it can be copied to the /etc/ directory. Thereafter, startup in the absence of a saved rcfile will use that configuration as default. Now if a distribution packager or system administrator wishes to expose their users to some of top's advanced capabilities they can do so gradually. Perhaps setting up graph mode for summary area task and memory display while retaining the %CPU sort could be tried. Or maybe showing colors, but better customized for a particular terminal emulator. Such possibilities are now endless. [ in exploiting this new capability, i hope that the ] [ other windows (alt display mode) aren't overlooked ] Reference(s): .

procps
procps is a set of command line and full-screen utilities that provide information out of the pseudo-filesystem most commonly located at /proc. This filesystem provides a simple interface to the kernel data structures. The programs of procps generally concentrate on the structures that describe the processess running on the system.
The following programs are found in procps:
- free - Report the amount of free and used memory in the system
- kill - Send a signal to a process based on PID
- pgrep - List processes based on name or other attributes
- pkill - Send a signal to a process based on name or other attributes
- pmap - Report memory map of a process
- ps - Report information of processes
- pwdx - Report current directory of a process
- skill - Obsolete version of pgrep/pkill
- slabtop - Display kernel slab cache information in real time
- snice - Renice a process
- sysctl - Read or Write kernel parameters at run-time
- tload - Graphical representation of system load average
- top - Dynamic real-time view of running processes
- uptime - Display how long the system has been running
- vmstat - Report virtual memory statistics
- w - Report logged in users and what they are doing
- watch - Execute a program periodically, showing output fullscreen
Reporting Bugs
There are a few ways of reporting bugs or feature requests:
- Your distributions bug reporter. If you are using a distribution your first port of call is their bug tracker. This is because each distribution has their own patches and way of dealing with bugs. Also bug reporting often does not need any subscription to websites.
- GitLab Issues - To the left of this page is the issue tracker. You can report bugs here.
- Email list - We have an email list (see below) where you can report bugs. The problem with this method is bug reports often get lost and cannot be tracked. This is especially a big problem when its something that will take time to resolve.
If you need to report bugs, there is more details on the Bug Reporting page.
Email List
The email list for the developers and users of procps is found at http://www.freelists.org/archive/procps/ This email list discusses the development of procps and is used by distributions to also forward or discuss bugs.
